Every few days I've been having a terrible runny nose and blocked sinuses like the awfulest cold you can imagine that lasted for about two days. I thought it was probably the autumn pollen - ragweed, or that big ornamental grass thing outside my bedroom window, and going away when the weather changed.
I'm actually having a reaction to the chlorine in the swimming pool. Ugh. It's a tissue reaction to the irritation of the chlorine, not an allergic reaction. So my normal seasonal allergy antihistamine didn't help one little bit.
Looks like I'm going to be swimming with a noseclip from here on out unless I'm in open water, and maybe experimenting with fun barrier methods like Vaseline up the nose. I'll have to see if it's a little less bad in the cooler of the two pools at our YMCA. People have also recommended neti pots (ewww) but I think a spray of nasal saline is more or less equivalent. I've also heard Atrovent up the nose does a great job preventing it as well, but I'll wait and see if non-drug approaches work first.
Ugh. What a pain.
I think this might be a great justification to buy an Endless Pool, don't you?
